づる耕耘爪も知られている。In recent years, up-cut tillage methods have been reconsidered in rotary tillage devices because of their advantage of improving soil crushability. In many of these systems, improvements have been made to the rotary tilling device so that it can be used in conjunction with the conventional down-cut method, making it possible to perform both down-cut and amp-cut tilling methods with a single device. There is also known a tilling claw that is attached to the tilling shaft of a tilling device that can be used for both down-cutting and up-cutting, and can be used as is when the tilling shaft is rotated in forward and reverse directions, and that has a horizontal blade.

ものである。In the above tilling device, when the tilling claws attached to the tilling shaft for down-cutting are used for up-cutting by reversing only the direction of rotation of the tilling shaft, the tilled soil will be removed along the shield cover. It takes a lot of power to release it from the rear of the car, so the power required is generally high. In addition, in a tilling claw for forward and reverse rotation that is fixed to the tilling shaft, the horizontal blade part, when cutting down or up cutting, causes the sieve part on the opposite side of the rotation direction to back hit and float on the tilling device. This causes the vibration to rise again. It has been found that this suction angle is very small and can be solved by shifting the tip of the tiller claw (lateral blade) by 2 to 3 degrees in the opposite direction to the direction of rotation. Therefore, in the present invention, when the tilling shaft is rotated in the forward and reverse directions, the base side of the attachment of the tilling claws is shifted in the opposite direction to the direction of rotation of the tilling claws to cover the suction angle, so that both down-cut and up-cut can be achieved. The purpose of the present invention is to provide a tilling claw for forward and reverse rotation that can accomplish the necessary cutting, reversing, and frame work.

するものである。In order to achieve this object, the present invention provides a tilling claw that is attached to a tilling shaft capable of forward and reverse rotation and can be used as it is when the tilling shaft is rotated forward and backward, and has a horizontal blade. This is characterized by being able to move back and forth around the central position of the tip in the front and back direction, outside the claw attachment provided on the tilling shaft, and setting the range of movement within the range where the horizontal blade does not hit back. be.

るから、操作が簡単である、等の効果が得られる。[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In the figure, numeral 1 is the tilling shaft of the rotary tilling device,
Brackets 2.degree. 2 are erected on the outer periphery of the tilling shaft 1, facing each other with a predetermined gap 3 therebetween. Bracket 2.
2 is formed with a rib 2a, and two receiving holes 4.4 are bored through it, and a tilling claw 5 for forward/reverse rotation that penetrates the mounting base into the gap 3, The mounting number is attached so that it can be slid back and forth using bolts and nuts 6.6. The tilling claws 5 for forward and reverse rotation are formed symmetrically with respect to the center line C, and are composed of a mounting part 5a, a vertical blade part 5b, and a horizontal blade part 5C. A blade edge 5d is formed on the outer edge of the blade 5C. The horizontal blade portion 5C is inclined so that its center line C is high and descends on both sides when viewed from the side. Further, the mounting portion 5a is provided with a long hole 7.degree. 7 through which the bolt/nut 6 is inserted. The tilling claws 5 are attached to the bracket 2 via bolts and nuts 6, and when the tilling shaft 1 rotates in the normal direction, it rotates in the direction of arrow down cut D, as shown in FIG. 1, and when it reverses, it rotates in the direction of arrow down cut D. It rotates in the U direction, but at this time, due to the phase change resistance applied to the tilling claw, the attachment part 5a side is rotated to the opposite side to the rotational direction of the tilling claw, centering on a point P where the rotation outer circumference R of the tilling claw intersects with the center line C. Tilling axis 1 within the length range of long holes 7 and 7
The angle ω is from the line Q passing through the center of
This eliminates the backlash phenomenon that occurs when the bottom surface of the soil hits the cultivated soil. Since the tilling claw of the present invention is configured in this way, the tilling shaft 1 is rotated forward or backward, and the tilling claw 5 is rotated in the down-cut D direction or the up-cut U direction to perform down-cut tilling work or up-cut work. Perform plowing and plowing work. At this time, the tilling work is performed while the attachment part 5a side of the tilling claw 5 is moved in the opposite direction to the rotating direction of the claw within the range of the long holes 7, 7, and the horizontal blade part 5C is driven into the soil. By shifting the angle by δ, there is no back striking where the back surface of the horizontal blade portion 5C on the opposite side to the rotation direction hits the tilled soil, and smooth tilling work is performed in both downcut and upcut. Therefore, there is little variation in the required power, and it is convenient to switch between down-cut and up-cut tilling operations simply by rotating the tilling shaft 1 in the forward or reverse direction. [Effects of the Invention] As explained above, according to the tilling claw for forward and reverse rotation of the present invention, the mounting part side of the tilling claw moves in the direction opposite to the rotational direction due to the forward and reverse rotation of the tilling shaft, and the side blade part Since the angle of the melon driven into the soil changes, it is possible to perform both down-cut tilling and up-cut tilling with less variation in the power required, and both tilling operations can be performed simply by switching the direction of rotation of the tilling shaft. Therefore, effects such as easy operation can be obtained.
